Got a good deal on a pair of barely used Corbeau racing seats for my '73 'bird. Seats didn't come with mounting brackets though. Corbeau lists two different part numbers for the mounting brackets. One part # is for '70 - '74, the other is for '75 - '81. the '70 - '74 brackets are more expensive, probably due to less demand. Up to this point I thought all the 2nd gen seats were interchangeable, that any year '70 - '81 seat would bolt directly into any 2nd gen without any issues. Is there really a difference with how they mount to the floor? Has anyone ever put '75 - '81 seats in an earlier car and did you encounter any problems? Obviously I'd like to get the cheaper brackets if they'll work just as good. Since the seat is a universal design and can be bolted into all kinds of cars, the difference must be with how the brackets mount to the floorboards.

Thanks for any info!

Keep us posted on any info that you gather.
I am wanting to upgrade to aftermarket seating myself and want to know about the mounting information to.

Didn't the floorpan change in 75 to accommodate cats? Not sure but I thinks so. This could be the reason. I think you would be okay with the cheaper brackets but you may have to make a spacer or something for the seats to sit evenly. I have a 70 and a 79. I will check this weekend to see if the brackets look different.

Yes,the floorpan changed in 75 for the cat. converter.

The floor pan side next to the hump is taller than the other side.

Okay, thanks for the info! I knew the floorpan changed for the cats but didn't realize it affected the mounting of the seats.

I'm thinking I'll look around for a set of trashed '71 - '74 seats and just scavenge the brackets off them. If I can't find any, then I'll buy the cheaper Corbeau brackets and make spacers as necessary.
